PSGallery Initializer
Overview
Intelligent PowerShell utility that automatically diagnoses and resolves the most common connectivity issues preventing PowerShell Gallery access across diverse Windows environments. Detects and configures TLS 1.2 protocol support which is required but often missing in older Windows installations, eliminating cryptic “unable to connect” errors. Validates NuGet provider installation and automatically installs missing providers with appropriate version selection for the PowerShell version in use.
Configures PowerShell Gallery as a trusted repository to bypass interactive confirmation prompts that break unattended automation. Tests actual connectivity to gallery endpoints with detailed diagnostic output including DNS resolution, SSL certificate validation, and proxy detection for rapid troubleshooting. Identifies and reports on proxy server configurations that may be blocking module downloads, providing actionable guidance for network administrators. Handles legacy PowerShell 5.1 environments on Windows 7/2008R2 systems where default security settings are incompatible with modern gallery requirements.
Essential for RMM deployments where scripts run across hundreds of customer environments with unknown configurations and security policies. Prevents automation script failures caused by missing dependencies that should be installed from the gallery. Dramatically reduces support time for “Install-Module not working” scenarios from 30+ minutes of manual troubleshooting to under 60 seconds of automated diagnosis and repair.
